Duality

Cash on your phone. As simple as Apple Pay, as fast as a text message, and as open as email. Duality is a self-custodial wallet that finally makes bitcoin feel like money you can actually use. Spend it, send it, get paid in it, in seconds, with no bank or middleman taking a cut. MONEY THAT MOVES LIKE A MESSAGE Payments settle over the Lightning network in seconds, not the three-day "pending" you're used to. Send, and it's done. TWO POCKETS, ONE WALLET Keep a Digital Cash balance to spend day to day, and a Bitcoin balance to hold. Swipe between them, and convert one to the other in a tap. ADD MONEY WITH A CARD Top up in a few taps. Buy with a card through Coinbase and it lands in your Digital Cash balance, usually within minutes. Duality shows the fees and the limits before you buy, and checks your country first, so you're never sent to a payment screen that won't take you. Card deposits are available in 45 countries. TOP UP FROM ANOTHER CHAIN Already holding stablecoins somewhere else? Send USDC or USDT from Tron, Ethereum, Solana, Base, BSC, Polygon and more, and it arrives as Digital Cash. Pick the network, enter the amount, show the code. GET PAID LIKE EMAIL Claim your own Lightning address: [email protected]. Anyone, on any Lightning wallet, can pay you. No app lock-in, no account numbers. PAY IN A TAP Tap to pay over NFC, or scan any QR code with Quick Pay. Save the people and places you pay often as Favourites and settle up in two taps. SIGN IN WITH A PASSKEY, BACKED BY YOUR RECOVERY PHRASE Create and unlock your wallet with your fingerprint or face, with no password to remember. Your recovery phrase is the backup that always works: save it when you set up, and it restores your wallet on any device, whatever happens to your phone. YOUR KEYS, YOUR MONEY Your keys are generated on your device and never leave it. There's no account, no email signup, and no company that can freeze, spend, or block your balance. No analytics or tracking, in the app or on our site. The only time your details leave the app is when you choose to buy, and then the payment provider gets only what it needs to process that purchase. SECURED BY BITCOIN Duality is built on Spark, a bitcoin layer 2, using the Breez SDK. Your money is secured by the most open, decentralised monetary network there is. Value you hold directly, not an IOU. Money without middlemen. Download Duality and try it today. Self-custodial means you're in control and responsible for your own access. Bitcoin's value can go up and down. Duality is not a bank and does not offer insured deposits.
